Error Unable To Parse Conf/bitbake.conf Parse Error

Contents

Being familiar with these topics will hopefully help if you start to use a project like Yocto and wonder what is going on. For now this is enough to use this class with our second recipe. 6.2. The BitBake Command1.5.1. Locating and Parsing Recipes2.3. this contact form

Events3.8. Exploring recipes and tasks Having now two recipes we are able to use and explore additional bitbake command options. Say that this target needs to run a patch function before the build task. There must be a way for you to express recipe preferences when multiple recipes provide the same functionality, or when there are multiple versions of a recipe. check here

Bitbake Commands

The execution process is launched using the following command form: $ bitbake For information on the BitBake command and its options, see "The BitBake Command" section. Immediate variable expansion (:=)3.1.6. This is a very typical way of using BitBake.

The cache location BitBake caches meta data information in a directory, the cache. However, there is still the question of a task's indirect inputs - the things that were already built and present in the build directory. Class inheritance To realize our configure/build chain we create a class that inherits the mybuild class and simply adds a configure task as a dependency of the build task. Bitbake List Tasks Because overrides have not been applied yet, A_foo is set to "X" due to the append and A simply equals "Z".

Locating and Parsing Recipes2.3. Bitbake Tutorial Here is an example that causes BitBake to produce a parsing error: fakeroot create_shar() { cat << "EOF" > ${SDK_DEPLOY}/${TOOLCHAIN_OUTPUTNAME}.sh usage() { echo "test" ###### The following "}" at the start This, and other notation is documented BitBake documentation chapter 3.1..* conf/bitbake.conf The conf/bitbake.conf contains a bunch of variables which, for now, we just take as they are. Setscene versions of a task have the string "_setscene" appended to the task name.

Fetchers4.3.1. Bitbake Addtask DEFAULT_PREFERENCE is often used to mark newer and more experimental recipe versions until they have undergone sufficient testing to be considered stable. But then when we tried to build the opie-image.bb (sample from recipes folder), it lead to the following error: *enggdesign at ubuntu:~/Desktop/OE/build$ export BBPATH=/Desktop/OE/build:/Desktop/OE/openembedded enggdesign at ubuntu:~/Desktop/OE/build$ bitbake opie-image.bb ERROR: Unable meta-tutorial/recipes-tutorial/second/second_1.0.bb DESCRIPTION = "I am he second recipe" PR = "r1" (1) inherit mybuild (2) def pyfunc(o): (3) print dir (o) python do_mypatch () { (4) bb.note ("runnin mypatch") pyfunc(d) (5)

Bitbake Tutorial

Local variables 10. You should realize, though, that it is much more flexible to set the BBPATH variable up in a configuration file for each project. From your shell, enter the following commands to Bitbake Commands do_showdata do_build do_listtasks do_patch ... Bitbake Manual About this tutorial 1.2.

Removal (Override Style Syntax)3.1.10. weblink And this is a good opportunity to introduce a nice and useful command flag, which is: verbose some debug output. The Task List2.6. The remainder of this section introduces several concepts that should be understood in order to better leverage the power of BitBake. 1.3.1. Recipes BitBake Recipes, which are denoted by the file extension Bitbake Clean

As an example, suppose you have two versions of a recipe (e.g. Checksums (Signatures)2.8. Currently, invalid timestamps are only considered on a per recipe file basis. navigate here Feedback 2.

In some cases, scenarios or examples that within the context of a build system are used in the manual to help with understanding. Bitbake Do_install The BitBake source tree currently comes with one class metadata file called base.bbclass. Of course, the base.bbclass can have much more depending on which build environments BitBake is supporting.

The required config files First a description of the needed files, then a short description to the content.

Once you have cloned BitBake, you should use the latest stable branch for development since the master branch is for BitBake development and might contain less stable changes. However, since the same word is used to describe packaged output from a project, it is best to maintain a single descriptive term, "recipes". 1.3.2. Configuration Files Configuration files, which are denoted Examples of Python functions are utility functions that you intend to call from in-line Python or from within other Python functions. Bitbake Do_configure However, if we define the following variable in a .conf file that BitBake parses, we can change that.

This directive behaves just like the include directive with the exception that BitBake raises a parsing error if the file to be included cannot be found. One common convention is to use the recipe filename to define pieces of metadata. We will use a local.conf later. 4.3. his comment is here DEBUG: Removed the following variables from the environment: GNOME_DESKTOP_SESSION_ID, XDG_CURRENT_DESKTOP, GNOME_KEYRING_CONTROL, DISPLAY, SSH_AGENT_PID, LANG, no_proxy, XDG_SESSION_PATH, XAUTHORITY, SESSION_MANAGER, SHLVL, MANDATORY_PATH, COMPIZ_CONFIG_PROFILE, WINDOWID, EDITOR, GPG_AGENT_INFO, SSH_AUTH_SOCK, GDMSESSION, GNOME_KEYRING_PID, XDG_SEAT_PATH, XDG_CONFIG_DIRS, LESSOPEN, DBUS_SESSION_BUS_ADDRESS,

Passing Information Into the Build Task Environment3.6. BitBake searches for class files in a "classes" subdirectory under the paths in BBPATH in the same way as configuration files. task-depends.dot: Shows dependencies between tasks. An Array of Challenges #2: Separate a Nested Array Extensible code to support different HR rules Why are Stormtroopers stationed outside the Death Star near the turbolaser batteries adjacent to Bay

However, if A is not set, the variable is set to "aval". Furthermore, building software packages contains often equal or very similar task. Consequently, when multiple "??=" assignments exist, the last one is used. While you might find it tempting to keep everything in one layer when working on a single project, the more modular you organize your metadata, the easier it is to cope

Variants - Class Extension Mechanism3.9. Setting a weak default value (??=)3.1.5. You could create an include file named foo.inc that contains the common definitions needed to build "foo". Summary 1.
